The undead. CPR makes you undead. On this pun and a whole lot of Zombie-trend right now, the Heart & Stroke Foundation of Ontario show what to do if you witness someone suffering a cardiac arrest. Step one, call 911. Step two, put your hands together and push on their chest like a crazy zombie-lady. It's not quite as catchy as British Heart Foundation - Staying Alive with Vinnie Jones, and it's three minutes long. Oh and for good measure, there's a twitter hashtag thrown in. #TheUndeading The Halloween-timing kinda saves. But only kinda.
